Sculpting grab tool causing pointy mesh?
Try using a bigger brush radius (F + drag to change).

Small radius:



Large radius:



Also try to drag close to the edge of the object.
When you grab closer to the center (thinking in 2D), you are really grabbing the side of the object, affecting geometry "closer" to the screen more than geometry near the actual center, which is at the edge of the visible portion of the object when in side ortho view.
